THE BLUE CROSS
under each arm. It is due to him to say that his fantastic physical strength was generally employed in such bloodless though undignified scenes; his real crimes were chiefly those of ingenious and wholesale robbery. But each of his thefts was almost a new sin, and would make a story by itself. It was he who ran the great Tyrolean Dairy Company in London, with no dairies, no cows, no carts, no milk, but with some thousand subscribers. These he served by the simple operation of moving the little milk cans outside people's doors to the doors of his own customers. It was he who had kept up an unaccountable and close correspondence with a young lady whose whole letter-bag was intercepted, by the extraordinary trick of photographing his messages infinitesimally small upon the slides of a microscope. A sweeping simplicity, however, marked many of his experiments. It is said that he once repainted all the numbers in a street in the dead of night merely to divert one traveller into a trap. It is quite certain that he invented a portable pillar-box, which he put up at corners in quiet suburbs on the chance of strangers dropping postal orders into it. Lastly, he was known to be a startling acrobat; despite his huge figure, he could leap like a grasshopper and melt into the tree-tops like a monkey. Hence the great Valentin, when he set out to find Flambeau, was perfectly aware that his adventures would not end when he had found him.
